What Is APR and How Does It Work?

Annual percentage rate (APR) is the yearly interest rate plus any fees you pay when you borrow money. APRs provide a bottom-line number that you can use to compare products from different lenders, credit cards or investments. 

Key Takeaways

• APR, or annual percentage rate, is the yearly cost of borrowing money — it includes both the interest rate and certain lender fees, making it a more complete picture of what you'll pay than the interest rate alone.

• The type of APR on your account can significantly affect your costs — fixed APRs stay the same over the life of a loan, while variable APRs fluctuate, meaning your payments could rise or fall over time.

• APR and APY measure opposite sides of the same equation — APR is what you pay to borrow money, while APY is what you earn on savings or investments, including compound interest.

• A lower APR doesn't automatically mean a better deal — always weigh the loan term, total fees and rate type together before committing to any financial product.

• To get a lower APR, focus on building your credit score, compare offers from multiple lenders and consider a balance transfer to reduce the interest you're paying on any current debt.

As a general rule, with comparable loan terms, the lower the APR the less money you'll pay over the course of a loan.

While APR is important, you should also consider factors like the type of interest you're being charged, fees, and the length of the loan. 

How Does the Annual Percentage Rate (APR) Work? APR Explained

APRs are expressed as an interest rate that’s a percentage of the total amount of money that you borrowed. Think of it like the “full price tag” of borrowing money. 

Several factors can influence the APR you pay for financial products like loans or credit cards:

1. Lender

2. Type of loan 

3. Your creditworthiness

4. Benchmark rates

5. Fees and other charges

Why Is APR Important?

Understanding your APR is important because it lets you know how much a loan, credit card, or other lending product will cost you in interest. Without a good understanding of APRs, you could accidentally pay hundreds (or even thousands) of dollars in interest unnecessarily. 

APR vs. Interest Rate

APR includes the interest rate, along with any fees that might included in the cost to borrow — think like an origination fee, if the lender issues one.

Annual Percentage Rate

• What it is: The total cost of borrowing money over a year, including the interest rate plus certain fees (if applicable).

• Where it applies: Loans, credit cards and mortgages.

• Why it matters: It gives a more accurate picture of the total cost of borrowing than just the interest rate alone.

Interest Rate

• What it is: The percentage charged only on the principal amount of a loan or credit card balance.

• Where it applies: Loans and credit cards.

• Why it matters: It affects how much interest accrues, but it doesn't include fees like APR does.

What Are the Different Types of APRs?

Different lenders offer varying types of APRs depending on the financial product. Here are a few of the most common APRs that you’ll come across:

👉 Fixed APR: Your interest rate stays the same over the life of a loan. This can help you enjoy predictability in payments. Some credit cards have fixed APRs, though it’s not common.

👉 Variable APR: Your interest fluctuates based on an underlying benchmark interest rate, such as the federal funds rate. If the benchmark rate rises then your interest rate—and your costs—will likely increase as well. But, if the benchmark rate drops then your rate could decrease.

👉 Purchase APR: Your interest rate is only applied to purchases made with a credit card if you carry a balance beyond the grace period. This is the standard APR for credit cards used for most everyday transactions.

👉 Promotional or introductory APR: A temporary lower interest rate (sometimes 0%) offered for a specific period when you open a new credit card or take advantage of a special offer. Once the promo period ends, the APR reverts to the standard rate.

👉 Cash advance APR: The interest rate you’ll be charged when you withdraw cash from your credit card which is typically higher than the purchase APR. Cash advances also often accrue interest immediately, without a grace period.

👉 Balance transfer APR: The interest rate applied when you transfer debt from one credit card to another. Balance transfer cards typically offer a lower introductory rate for a limited time, which can help you save money on interest in the short term.

👉 Penalty APR: A higher interest rate that’s triggered when you violate your credit card’s terms—such as making a late payment or missing a payment entirely. This rate can be significantly higher than your standard APR and may last indefinitely.

APR vs. APY 

While annual percentage rate (APR) tells you the interest you pay on a credit card or other loan plus any fees, annual percentage yield (APY) tells you the amount of interest you’ll earn from a certain investment product, including compound interest. These two metrics are essentially two sides of the same coin:

1. APR meaning = interest paid on money that you borrow

2. APY meaning = interest earned on money that you invest or save

APR Example

Say that you take out a one-year personal loan of $2,500 that has an APR of 5%. If you constantly pay down your balance with equal monthly payments then you'll repay your loan in 12 monthly payments of $214.02 and you'll pay $68.22 in total interest.

APY Example

Say that you put $2,500 into a high-yield savings account that pays 5.00% APY for one year. This account compounds monthly and you'll earn $125 in interest by the end of the year assuming that you don’t add or withdraw any more money.

What Is Daily Periodic Rate

Your daily periodic rate is similar to APR, APY and interest, and it's a way to calculate the amount of money that you’ll pay in interest when borrowing money. 

Daily Periodic Rate

• What it is: The APR divided by 365 days — or 360, depending on the lender. It determines how much interest accrues each day on your balance.

• Where it applies: Credit cards and variable-rate loans.

• Why it matters: The higher your DPR, the faster interest accumulates, especially if you carry a balance.

APR vs. interest rate: The APR and interest rate are similar. But, APRs include the interest rate plus any and all fees, giving you a more clear picture of your total cost.

How To Calculate APR

Most lenders will advertise the APR they’re offering for a certain product. If not, then here’s how to calculate APR on a credit card or other loan:

(((Interest + Fees) / Loan amount) / Days in loan term) × 365 × 100 = APR

For example, say you borrow $5,000 with a 10% interest rate, a 5% origination fee and a three-year repayment term. Here’s how you’d calculate the loan’s APR using the above formula:

1. Multiply $5,000 by 0.10 and then 3, giving you interest charges of $1,500

2. Multiply $5,000 by 0.05, giving you an origination fee of $250

3. Divide interest and fees of $1,750 by $5,000, giving you 0.35

4. Divide 0.35 by 1095 (the number of days in your loan term), for a result of 0.00031963

5. Multiply 0.00031963 by 365, giving you an APR of 0.116666667

6. Multiply that by 100 to convert the APR to a percentage of 11.67%

Conversely, you can also use an online personal loan calculator to help understand the interest you’re paying.

What Is a Good APR Rate?

Instead of searching for the lowest APR, it’s better to examine all factors of a loan together like the type of interest, total fees, and loan length. 

APRs can sometimes be misleading by themselves. However, you can use the following benchmarks to understand the standard rates for different types of financial products:

1. Credit cards: 21 to 30%

2. Personal loans: 10% to 20%

3. Auto loans: 6% to 7% for used and around 11 to 12% for new

4. Mortgages: About 8%

Many credit cards will offer introductory rates of 0% which can help you avoid paying interest while you pay down debt. However, be wary that your rate will increase once the introductory period ends.

How To Get a Lower APR

You can take steps to get a lower APR with your lender. Try these tips:

• Improve your credit score

• Negotiate with the lender

• Try a balance transfer to move existing debt to a lower-interest card

• Pay off any balances you currently have

Final Take

Now that you have a better understanding of what APR is and how it works beyond just as your interest rate, you'll be well-equipped to secure an attractive rate on your next credit card, personal loan or mortgage.

FAQs

What is the relationship between APR and the true cost of credit?

The APR (Annual Percentage Rate) represents the total cost of borrowing over a year, including interest, certain fees, and the compounding schedule. In general, the higher the APR the higher the true cost of credit and vice versa. 

Is a lower APR always better?

Not necessarily. Low APRs can sometimes be misleading which is why you should always consider factors like fees, the type of APR, and the loan term before making a decision.

What happens when my 0% intro APR ends?

Once the 0% intro APR period ends, your card's APR will adjust to the standard APR as outlined in the terms in conditions. It's often a variable rate, and hovers somewhere around 20%, give or take. Your balance will immediately begin accruing interest as well, if you're carrying any still. Some store cards will offer this 0% intro APR, which is great if you need time to pay off your purchases. Still, it's generally best to pay off your balance before the intro APR ends.

What is the best APR for a credit card?

This depends on your financial goals and needs. Some credit cards offer 0% introductory rates while others prioritize rewards. Read on to learn more about the top credit cards of 2026. 

How does an APR for mortgages differ from a more traditional interest rate?

A mortgage APR includes the interest rate plus additional costs like origination fees, discount points, and lender fees. In comparison, the interest rate only reflects the cost of borrowing the principal, excluding fees.

What is a good APR for a used car?

By itself, the APR does not offer enough information to know whether you are getting a good deal. In addition to the APR, the Consumer Financial Protection Bureau recommends weighing the total loan amount, length of the loan, and monthly payment. Learn how to calculate APR on a car loan.

Does APR affect my monthly payments?

Yes, APR indirectly affects your monthly payments because it includes both the interest rate and certain fees, which impact the total cost of borrowing.

How is APR calculated on a credit card balance?

APR on a credit card balance is calculated using the daily periodic rate (DPR), which determines how much interest accrues each day.

Key Terms

• Annual percentage rate (APR): The yearly cost of borrowing money, expressed as a percentage, that includes both the interest rate and certain fees charged by the lender — such as origination fees.

• Interest rate: The percentage charged only on the principal balance of a loan or credit card. It doesn't include lender fees, so doesn't show the full scope of the cost to borrow, compared to APR.

• Fixed APR: An interest rate that stays constant for the life of a loan or credit card. It makes your monthly payments predictable, regardless of any shifts in the market.

• Variable APR: An interest rate that can rise or fall over time, meaning your borrowing costs may change from period to period.

• Introductory APR: A temporarily reduced rate — sometimes 0% — offered for a set period when you open a new credit card or use a promotional offer. The rate reverts to the standard APR once that period ends.

• Daily periodic rate (DPR): The APR divided by 365 days, or 360, depending on the lender. It determines how much interest accrues on your outstanding balance each day.

• Annual percentage yield (APY): The rate of return earned on a deposit or investment account over one year, including the effect of compound interest — the savings counterpart to APR.

• Balance transfer APR: The interest rate applied when you move debt from one credit card to another, often featuring a lower introductory rate for a limited period.
